Buying Guide
Choosing the right AGM battery for your trolling motor involves considering a few key factors. Here’s what to keep in mind:
- Capacity (Ah): This determines how long your trolling motor will run on a single charge. Higher Ah means longer run times. Consider how long you typically spend on the water and choose accordingly.
- Voltage: Most trolling motors require 12V batteries. Make sure the battery you choose matches the voltage requirements of your motor.
- Size and Weight: Consider the space you have available in your boat and the weight capacity. AGM batteries can be heavy, so make sure your boat can handle the extra load.
- Deep Cycle vs. Starting: Deep cycle batteries are designed to be discharged and recharged repeatedly, making them ideal for trolling motors. Some batteries, like the Optima BlueTop, can handle both starting and deep cycle applications.
- Brand Reputation: Stick with reputable brands known for producing high-quality batteries. Reading reviews and doing your research can help you make an informed decision.
- Budget: AGM batteries range in price. Set a budget and look for the best battery that fits your needs within that range.
